The interrelation between the physicochemical properties 
of macromolecules and the hydrodynamic parameters of a turbulent flow 
of diluted polymer solutions in a cylindrical channel has been analytically 
determined. The possibility of estimating of the molecular characteristics 
of high-molecular polymers with the use of the turborheometric method 
has been considered. The antiturbulence efficiency of polyhexane used 
in energy-conserving technologies of pipeline transport of hydrocarbon 
materials has been analyzed on the basis of comparison of the molecular 
masses of polymers determined by different methods.
